GAS-PRESSURE REGULATOR.

SUECFICATION forming part of Letters Patent No. 348,172, dated August 24, 1886.

Application filed July 3, 1886. Serial No. 207,061. (No model.)

T0 all whom it may concern:

Be it known that l, Cummins RUrnEenT, of Cleveland, in the county ol' Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Gas- Pressure Regulators; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in gaspressure regulators adapted to be used between the gasmeter and service-pipe to regulate and give the uniform desired pressure of gas at the burner, and it consists in certain features of construction, and in combination ofparts,here inafter described,and pointed outin the claims.

ln the accompanying drawings, Figure l is a side elevation of my improved gas-pressure regulator. Fig. 2 is an elevation in section through the center of the regulator'.

A represents the valve-casing, having four nozzles arranged in the same plane. To the nozzle a is attached the pipe leading to the meter. The nozzle a is attached to the service-pipe. Through the nozzle a? access is had to they casing A, for facing the valve-seat and inserting the valve, (be. This nozzle is closed with a plug, a. The nozzle a" has attached the casing B, in which the float D operates. Thislatter nozzle has a head or diaphragm, a5, east in. The casing Bhas a removable cover, b, at the top, and at the bottom is soldered or otherwise secured to the lower end of the cylindrical openended tube C, and the two are soldered or otherwise attached to the nozzle a".

F is a diaphragm cast in the casing A, in which diaphragm is seated the valve E. This diaphragm is substantially the same as had in ordinary globe-valves, except that the part f slopes upward and backward to near the eenter of the head a5, leaving room for the oriiice c on the side of the diaphragm next the service-pipe, said orifice opening above into the tube C. On the other side ofthe partf of the diaphragm F is a small orifice in the center of the head a5, through which orifice passes the stem e of the valve E, the latter opening downward. The upper end of the stem c is attached to the center of the float usually by jam-nuts e', arranged above and below the lloat, with packing between to form a tight joint.

The chamber B of the casing B, in which operates the float, is llled with glyeerine or other suitable fluid for scaling `the iloat up to about the line xx. The casing B and the float are preferably of about the form shown in Fig. 2, the curves d and d performing important functions-to wit, they retard quick vertical movements ofthe loat through the liquid and keep the valve steady. Heretofore a double or two-faced valve was considered necessary, involving an arrangement of the interna-l diaphragm that greatly retarded the flow of gas from the meter tothe service-pipe. Vith my improved construction, by means ofthe sloping part f of the diaphragm, the arrangement of parts is such that a single valve is used, and the Ilow of gas to and from the valve is not obstructed.

In operating the device, when there is little or no pressure of gas, the valve is depressed by gravity and remains open, the gas passing unobstructed from the meter to the servicepipe and through the orifice c up under the float. Then the maximum pressure desired is reached, the pressure under the float raises the latter and closes the valve. New, if one or more burners are'lighted, the pressure in the service-pipe is of course reduced, and as a service-pipe by means of the orilice c is in open relation with the under side of the iloat the pressure that buoys the float is reduced, when the latter descends and opens the valve more or less, according to the reduction of pressure in the service-pipe and under the float. The opening of the valve of course admits gas to supply the deficiency caused by consumption at the burners. In this manner the pressure of gas at the burner is regulated and kept unform regardless of the pressure at the meter. rhe aggregate weight of the float, valve, and valvestem as compared with the area in crosssection of the float at the largest part thereof is such as to give the desired pressure. lf a greater pressure is desired, more weightis added to the float.

My improved device, on account of its single valve and the simplicity of its general censtruction, can be made ata greatly reduced IOO initial cost, as compared with the gas-pressure regulators heretofore in use, and will be found reliable and desirable in every respect.

l. In a gaspressure regulator, the combination, with a single-faced valve anda float for operating thc valve, arranged substantially as indicated, of a diaphragm in the valve-easing forming a seat for the valve, said diaphragm on the side next the service-pipe being made at an acute angle', and joining the upper wall of the casing near the center thereof, substantion, with a single-faced valve and a float conneet-ed with the valve for operating the same, said iioat being located in a suitable chamber and fluid-sealed, of a valve-easing and diaphragm, arranged substantially as shown, and an orifice in the valve-easing leading under the float and discharging on the side of the diaphragm next the service-pipe, the parts being arranged substantially as described.

4. In a gas-pressure regulator, the combination, with a valve-casing, valve, diaphragm, and float, arranged substantially as indicated, of the head a5, arranged between the valvechaniber andthe iloat-chamber, said head having an orifice, c, and an orifice for the passage of the valve-stem, substantially as set forth.

In testimony whereof I sgn'this specifica` o tion, in the presence of two witnesses, this 19th day of June, 1886.

CHARLES RUPRECH'.
